Decoherence from spin environments

Mostrar todas las versiones(2)

We examine two exactly solvable models of decoherence-a central spin-system, (i) with and (ii) without a self-Hamiltonian, interacting with a collection of environment spins. In the absence of a self-Hamiltonian we show that in this model (introduced some time ago to illustrate environment-induced s...
